Hi omovik,

Good observation on the external monitor piece. Check if the notebook display works fine when you enter BIOS (F2 during start-up) or during diagnostics (Fn+Power). If the issue persists on these steps then it's a faulty LCD. Do keep me updated on the status.

Thanks and Regards.
Kiran Kumar.

    Hi omovik, It looks like the LCD screen on the computer has failed. You may use the below link and check warranty status of your computer:http://dell.to/193rSG3 If the computer is in warranty do send me the system service tag and customer details like customer name, place of purchase, shipping address, email address and phone number to my email address Kiran_kumar_a@dell.com. I will check and see what can be done. If the computer is out of warranty you may contact the out of warranty repairs team on 18002884410 (U.S only) or a local technician. They can help you further. Thanks and Regards. Kiran Kumar. #iworkfordell

Well it is most likely a issue with the Video driver as you are able to boot to the safe mode.I would suggest going back to the safe mode and deleting the present driver for the video from the device manager.before you restart the system just download the latest version from the support.dell.com so that you can reinstall it.Also check in the graphic properties which screen is set to be the defuat.Incase still not working i would suggest reinstalling the operating system before replacing any hardware.

SOURCE: D800 laptop will not display on external monitor

Most laptops go into standby mode when the lid is closed. To stop this, (Windows XP) click Start, Control Panel, Performance and Maintenance, Power Options, then click on the Advanced tab, select "Do nothing" in the drop-down for "When I close the lid of my portable computer"

No. You just basically need a VGA cable. Check your video settings.

Sounds like your computer has just bit the dust, do your self a favor and purchase a new one. This time buy an XP, it might be a little bit more, but you get what you pay for.

SOURCE: dell latitude D610. Screen goes black. External Monitor OK.

Make sure you have not accidentally used the FN+F5 key
That combination sets the laptop to use an external display.

If using that does not give you a display take a small torch (flashlight if in USA) and shine it at an angle on the laptop screen.
If you can see any sort of picture you would be looking at replacement of some minor parts to the laptop screen

Hope this gives you the information you need. If not add any extra information you may have and lets see if we can FixYa

Why does my monitor start as white when I turn it on? THe mouse pad does not work as well.


Monitor cable disconnected internally?

follow http://www.insidemylaptop.com/replace-screen-on-dell-latitude-e5420-laptop/
and disconnect, clean and reconnect ALL monitor related cables. (You may need a new screen if that fails)

You may check your laptop by connecting an external monitor first.

Why does my acer aspire one not boot with a hard drive besides the screen going white when connecting the charger?


If you can plug an external monitor into the laptop, and if it works ok, the video on the laptop is going bad (chip or cable). If an external monitor works, I recommend you back up your data asap, if possible to an external hard drive. No way of telling how long before other things go wrong, and the price of fixing it might cost more than getting a new laptop.

You could have a loose video cable connection that attaches to the motherboard or you may have a faulty on-board video.
Try connecting an external monitor to your Dell, power up the external monitor fist and then boot up the Dell laptop. The video will automatically divert to the external monitor if the on-board video is OK.
This means the video cable/connector needs re-seating or the video cable is faulty.

White screen


The white screen you are getting is it just right after turning on the computer? If yes it means that you were not able to see the Dell logo correct?

Try connecting an external monitor thru VGA. While monitor and laptop is on with white screen please do this. Hold down Fn key then press F8 at the same time. This will toggle the display from the laptop to external monitor. If laptop displays to external monitor means that laptop LCD needs to be replaced.

If you do not have an external monitor try this.
While laptop is OFF. Do this. Hold down the D key then press power button at the same time.
Check if the laptop will display colors the whole screen. If you still see white screen then LCD needs replacement.

LCD mean LCD panel or the whole screen together with LCD cable and Inverter.

Hope this helps.

Here is problem in my newly laptop Dell Inspiron 1564. When i start it it screen shows totally white . After again and again start it is start and after some time or during my working it is again...


Try to plug in an external display (take the one of your desktop PC if you have). If it works on an external as normal then the problem is physical and it has to do only with the screen (new screen or invertor, or screen cable). If the same problem happens on the external monitor, do not touch the screen part. the problem then must be either video card or motherboard. I suggest try to do this trick with the external monitor to find the problem for youself and then use your warranty and bring it to the shop to have it repaired.

The screen is not coming on at all. i connected


With the external monitor connected, try holding down the FN key and pressing one of the F keys at the top of the keyboard that has a Monitor icon on it. This should turn off the external screen and show the laptop screen. If you press it a 2nd time, BOTH screens should show up. If still blank, Press again until the External Monitor comes back on. Then go to www.dell.com/support and go to Drivers for your Model. Then download and re install the VIDEO or DISPLAY Drivers. This should fix it if its a missing driver. If STILL no display on the laptop, call Dell.

Replacing the display should solve it.Maybe the inverter but most likely its the display itself.

Acer aspire 5220 booting problem


Try connecting to an external monitor. If it displays on the external monitor then the LCD is probably dead. If it doesn't display on the external monitor, its a problem with the video card.
